Vinny,

Why did you choose a P5X? I would think your hull would like more bow lift than a P5X can deliver. Did you have it trimmed higher than last year to hit top speed?

Dave,
I went with the P-5X on Throtle-Ups recommendation. The boat did ride a bit different. Like you said, not as high from the bow. I'll see what my Bravo wheel gives me. Of course, the weather doesn't look good here for the weekend.

The reason I'm testing a 5 Blade is to hold 1300HP and use a 2" shorty drive. Without a shorty drive, I can't see how a 5 blade could help a checkmate. But stranger things have happened.

BTW the weather here looks bad too. %#@*&

I am beginning to think that I may have made a mistake with going to a 5 blade. My thoughts were to get a bit less slip over a 4 blade. Besides, Throttle-Up thought it would work as well. It still may, only further testing will tell. Luckily, they will exchange the prop for a different style and or oitch.

What slip did your bravo have last year? You may want to talk to Brett at BBlades.com. I've dealt with him for years, and he's been very knowledgeable on checkmate hulls.

I got 9% slip with the Hydromotive and 14 1/2 % slip with the Bravo. I am not sure how or if the Imco lower drive I have on now will effect the slip numbers as compared to standard Bravo 1 H.P. drive from last year.

From my testing a nose-coned lower will usually reduce your slip. Since there is less blowout, Especially at high speed. Your slip results are very similar to mine. If you want to use the 5 blade you will most likely need to raise your drive height about 1". I realize that would require a 2" shorty with a spacer. It's only money........

This weekend was another bust weather wise. I plan on taking some time off from work this week to give it a run with my 26" Bravo. I'll let you know. I am going to try to avoid going to a shorty.
